Video shows new cap put on leaking BP Gulf well

Undersea video showed BP robots landed a new,
tighter-fitting cap on top of the gushing Gulf of Mexico oil leak
Monday, raising hopes that the crude could be kept from polluting
the water for the first time in nearly three months.

Placing the cap on top of the leak was the climax of two days of
delicate preparation work and a day of slowly lowering it into
position. The capping project - akin to building an underwater Lego
tower - is just a temporary fix, but the oil giant's best hope yet
for containing the spill.

Around 6:30 p.m. CDT, live video streams trained on the wellhead
showed the cap being slowly lowered into place, 11 hours after BP
Chief Operating Officer Doug Suttles said the company was close to
putting the seal in place. Company officials did not comment on the
operation Monday evening or say how long it would take to latch the
cap permanently in place.

From the White House to Gulf Coast marinas and town halls, all
eyes were on the slow, deliberate process unfolding a mile below
the sea. President Barack Obama is getting repeated updates, his
adviser David Axelrod said. Residents on the coast were skeptical,
though, and know that even if the gusher is contained, the disaster
will be far from over.

The 18-foot-high, 150,000-pound metal cap will be tested and
monitored to see if it can withstand pressure from oil and gas
starting Tuesday morning for six to 48 hours, according to National
Incident Commander Thad Allen. The cap will be tested by closing
off three separate valves that fit together snugly like pairs of
fists, choking off the oil and blocking it from entering the Gulf.

BP doesn't want the flow of oil to stop instantaneously, said
Don Van Nieuwenhuise, director of Professional Geosciences Programs
at the University of Houston. Shutting the oil off too quickly
could cause another explosion, he said.

"Rather than like a train running into a brick wall, it'll be
more like putting the brakes on slowly," he said. "That's what
they're aiming for. You can keep the brakes on and everyone arrives
alive, or you hit the wall and have big problems."

Even if the cap works, the blown-out well will still be leaking.
But the newer, tighter cap will enable BP to capture all the oil,
or help funnel it up to ships on the surface if necessary.

One of those ships, the Helix Producer, began operating Monday
and should be up to its capacity of collecting roughly 1 million
gallons of oil a day within a few days, Chief Operating Officer
Doug Suttles said.

A permanent fix will have to wait until one of two relief wells
being drilled reaches the broken well, which will then be plugged
up with drilling mud and cement. That may not happen until
mid-August.

Meanwhile, the Obama administration issued a revised moratorium
on deep-water offshore drilling Monday to replace the one that was
struck down by the courts as heavy-handed. The original moratorium
halted the approval of any new permits for deep-water projects and
suspended drilling on 33 exploratory wells in the Gulf. The new
ban, in effect until Nov. 30, does not appear to deviate much from
the original moratorium, as it still targets deep-water drilling
operators while defining them in a different way.

Work on the new capping operation began Saturday with the
removal of a leaky cap that captured about 1 million of the 1.5
million to 2.5 million gallons of oil the government estimates is
spilling from the well every day.

Engineers will be watching pressure readings. High pressure is
good, because it would mean the leak has been contained inside the
wellhead machinery. But if readings are lower than expected, that
could mean there is another leak elsewhere in the well.

"Another concern right now would be how much pressure the well
can take," and whether intense pressure would further damage the
well, said Eric Smith, associate director of the Tulane Energy
Institute.

Gulf residents closely watched the operation, knowing the damage
already done to the biologically rich Gulf and the coast's two
leading industries, fishing and tourism.

"I think we're going to see oil out in the Gulf of Mexico,
roaming around, taking shots at us, for the next year, maybe two,"
said Billy Nungesser, president of Louisiana's oil-stained
Plaquemines Parish. "If you told me today no more oil was coming
ashore, we've still got a massive cleanup ahead."

BP "can't do much, but they know how to drill wells," dock
master Jimmy Beason said at a marina in Orange Beach, Ala. "I
think that by the end of the month it will be stopped, and this
work with the cap is part of it. I see the light at the end of the
tunnel."

As of Monday, between 89 million and 176 million gallons of oil
had poured into the Gulf, according to government estimates.
